Why does't the hash power of BSV surpass that of BTC?

Because of profitability. I don't think it will take very long before this will flip around though. With consistent big blocks BSV only needs to be at a fraction of the BTC price to make it more profitable.

To achieve consistent big block, we need more applicaion like Weather SV. That is why I want Nakasendo badly. Only elite develpers now can develop on BSV blockchain.
